2. OBJECTIVES
1. Plot the gain frequency response of a first-order (one-pole) R-C low-pass filter.
2. Determine the cutoff frequency and roll-off of an R-C first-order (one-pole)
low-pass filter.
3. Plot the phase-frequency of a first-order (one-pole) low-pass filter.
4. Determine how the value of R and C affects the cutoff frequency of an R-C low-
pass filter.
5. Plot the gain-frequency response of a first-order (one-pole) R-C high pass
filter.
6. Determine the cutoff frequency and roll-off of a first-order (one-pole) R-C
high pass filter.
7. Plot the phase-frequency response of a first-order (one-pole) high-pass filter.
8. Determine how the value of R and C affects the cutoff frequency of an R-C
high pass filter.
